Question

Show transcribed image textA rigid beam of weight W =800 N hangs from three equally spaced wires made of steel (marked S) and aluminum (marked A), as shown in the figure. The diameter of the wires of 1/8 cm. Before they were loaded, all three wires had the same length a,- What temperature increase delta T in all the wires would result in the entire load being carried by the steel wire? b.- Determine the final elongation of the structure. Take Es=200 GPa, EA=GPa, as = 12x10-6/ degree C and aA =23x10-6/ degree C.
